signor to The Spooner Dryer & Engineering Company Limited, Ilkley, England, a British company Application August 4, 1949, Serial No. 108,454 In Great Britain August 4, 1948 2 claims. 1

The present invention relates to improvements in machines for the treating of sheet or web material by means of fluid streams, of the type in which the material is displaced continuously or step by step in a vertical or substantially vertical plane or planes.

The invention is especially applicable to apparatus of this type wherein the material is moved relatively to nozzles disposed on one or both sides of the material, for the purpose of impacting thereon fluid streams for the drying, washing, scouring or other treatment of a textile web fabric, a band of paper or other web material.

According to the present inventionA material being treated is guided along a given path by a plurality of bars or rollers extending across the path and which are mounted on pairs of levers so that by angular displacement of the levers the bars or rollers can be displaced to facilitate the threading of fresh material through the apparatus.

Preferably displacement of the bars or rollers is eected by individual, group or common control means. Preferably the material is passed along a given path in a conned space and the bars or rollers are disposed alternately on opposite sides of the run of the material. The supporting levers may be pivotally mounted to the framework of the apparatus on opposite sides of the run of the material. Preferably the bars extend horizontally across the path of the material.

The invention will be further particularly described by way of example with reference to the accompanying drawings in which:

Fig. 1 is a side elevation of part of an apparatus embodying the present invention, and

Fig. 2 is a sectional elevation along the line II-II.

A web of material I0 is conveyed along a given path vertically or substantially vertically relatively to nozzles I I disposed on either side of the web for the purpose of impacting uid streams thereon for treatment of the web. Members I2, I3 and I4 are disposed in staggered formation at the extremities of levers 33 and 34, 35 and 3B, and 31 and 38 respectively, which are pivotally mounted on nozzle supporting plates I9 and 20 by means of brackets 2I. The members I2, I3 and I4 may conveniently be in the form of bars, rods or rollers. The bars I2, I3 and I4 are disposed transversely to the path of the material.

Adjacent bars are interconnected with one another by means of strips 22. The upper bar I2 is connected by means of strip 23 to crank 24 2. keyed to shaft 25 rotatably mounted in framework 26 of the apparatus and carrying at its other end a handle 21.

In the normal operating position the levers 33, 34, 35, 36, 31 and 38 are horizontal or substantially horizontal. Rotation of the handle 21 in a clockwise direction as seen in Fig. 1 causes strip 23 to descend thereby rotating levers 34 and 33, 38 and 31 in a clockwise direction, and rotating levers 36 and 35 in an anticlockwise direction, thereby displacing the bars out of the immediate range of the path of the web so as to allow a fresh web to be readily threaded through the machine. Anti-clockwise rotation of lever 21 returns the bars to the normal position and the bars serve to guide the web along the given path.

The weight of the lever 21 may be suicient to retain the bars in their normal working position or alternatively spring means may be used to retain the bars in their operating position. The handle 21 may be conveniently retained in the normal operating position by means of pin and socket mechanism 28,

Whilst only three bars I2, I3 and I4 are shown in the drawings, it will be appreciated that the invention is in no way limited to the particular number of bars shown. For example a satisfactory arrangement has been found to comprise 12 bars in each vertical column.

I claim:

1. An apparatus for the treatment of web material including in combination a treatment chamber having oppositely disposed walls providing for the passage of the web therethrough. pivotal mounting means at spaced points lengthwise of the chamber and alternately attached to the oppositely disposed walls, a plurality of pairs of spaced parallel levers mounted on the pivotal means and extending inwardly of the chamber, web guide means supported at the ends of each pair of levers, strips interconnecting each pair of levers with the adjacent pair of oppositely disposed levers, an operating handle, and a strip connecting said operating handle with one of said levers.

2. An apparatus for the treatment of web material including in combination a treatment chamber having oppositely disposed walls providing for the passage of the web therethrough, pivotal mounting means at spaced points lengthwise of the chamber and alternately attached to the oppositely disposed walls, af'plurality of pairs of spaced parallel levers mounted on the pivotal means and extending inwardly of the chamber, web guide means supported at the ends of each 3 pair of levers, strips interconnecting each pair of levers with the adjacent pair of opposltely disposed levers, an operating handle, a strip connecting said operating handle with one of said levers, and nozzles on said walls for directing 5 iluid therethrough on to said web.
